Hisako sells dolls at her doll store. If she sells a doll for $35, and there is 6% sales tax, what is the tax amount a customer
Sloan [31]

Given:

The price of a doll = $35

Sales tax = 6%

To find:

The tax amount that a customer will pay on one doll.

Solution:

The price of doll is $35 and the sales tax is 6%, so the tax amount on a doll is 6% of 35.

\text{Tax amount}=35\times \dfrac{6}{100}

\text{Tax amount}=\dfrac{210}{100}

\text{Tax amount}=\dfrac{21}{10}

\text{Tax amount}=2.1

Therefore, the tax amount that a customer will pay on one doll is $2.1.

Dont guess!<br> I will mark brainliest if its correct!<br> Also no links!
GREYUIT [131]

Answer:

The correct answer will be; B or 40.

Step-by-step explanation:

Because when the ratio of boys changed from 8 to 32, it increased by "time 4" (8*4 = 32), so the same pattern will be followed for girls, multiplying the number that you already have by four; 10 (amount of girls given) * 4 = 40.

Hope this helped, Good Luck!
